Now for the shiny new Realtek offering. If it wasn't for the ESP32 just arriving, this module might have been a big hit. Heck, it still may, what do I know - but for now it seems stuck to the sidelines.

CPU: Cortex M3 @ 166MHz
RAM: 48KB available to user
Flash: 1MB
WiFi: 802.11n up to 150Mbps
GPIO: Up to 21
I2C: 3
SPI: 2
PWM: 4
UART: 3
ADC: 0 (has a 10-bit ADC, but used internally for the radio)

A breadboard compatible RTL8710 module, essentially a replacement for the NodeMCU, at least in theory ;) We'll see how the software support matures.
